Application of a suitable type of methane reforming as well as online monitoring tools and a holistic knowledge about possible degradation mechanisms can limit degradation rates. Here, we compare direct internal reforming and external methane reforming on a large planar SOFC with an active area of at different operating temperatures and methane flow rates. To do so, the measured temperature distribution, applied electrochemical impedance spectroscopy and its advanced tool distribution of relaxation times (DRT) as well as results from post mortem microscopic analysis are used. We observed that the ohmic resistance and high frequency peaks in the DRT spectra seem to be influenced not only by the average cell temperature but also by direct internal reforming (DIR) conditions. Furthermore, we observed that high temperature gradients induced by DIR could lead to or accelerate damages of the cells structure and the sealing. The results presented in this work are useful to control or manage safe SOFC operation with C containing fuels for real world SOFC applications. 001009728 536__ $$0G:(DE-HGF)POF4-1231$$a1231 - Electrochemistry for Hydrogen (POF4-123)$$cPOF4-123$$fPOF IV$$x0 001009728 536__ $$0G:(DE-Juel1)SOFC-20140602$$aSOFC - Solid Oxide Fuel Cell (SOFC-20140602)$$cSOFC-20140602$$fSOFC$$x1 001009728 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 001009728 7001_ $$00000-0003-2434-0635$$aKönigshofer, Benjamin$$b1 001009728 7001_ $$0P:(DE-HGF)0$$aSchröttner, Hartmuth$$b2 001009728 7001_ $$0P:(DE-HGF)0$$aFitzek, Harald$$b3 001009728 7001_ $$0P:(DE-Juel1)129636$$aMenzler, Norbert H.$$b4 001009728 7001_ $$0P:(DE-HGF)0$$aHochenauer, Christoph$$b5 001009728 7001_ $$0P:(DE-HGF)0$$aSubotić, Vanja$$b6 001009728 773__ $$0PERI:(DE-600)1491915-1$$a10.1016/j.jpowsour.2023.233449$$gVol. 581, p. 233449 -$$p233449 -$$tJournal of power sources$$v581$$x0378-7753$$y2023 001009728 8564_ $$uhttps://juser.fz-juelich.de/record/1009728/files/1-s2.0-S037877532300825X-main.pdf$$yOpenAccess 001009728 8564_ $$uhttps://juser.fz-juelich.de/record/1009728/files/full_Paper.pdf$$yOpenAccess 001009728 909CO $$ooai:juser.fz-juelich.de:1009728$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 001009728 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129636$$aForschungszentrum Jülich$$b4$$kFZJ 001009728 9131_ $$0G:(DE-HGF)POF4-123$$1G:(DE-HGF)POF4-120$$2G:(DE-HGF)POF4-100$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-1231$$aDE-HGF$$bForschungsbereich Energie$$lMaterialien und Technologien für die Energiewende (MTET)$$vChemische Energieträger$$x0 001009728 9141_ $$y2023 001009728 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 001009728 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2022-11-13 001009728 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 001009728 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2022-11-13 001009728 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2023-08-28 001009728 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2023-08-28 001009728 915__ $$0StatID:(DE-HGF)1160$$2StatID$$aDBCoverage$$bCurrent Contents - Engineering, Computing and Technology$$d2023-08-28 001009728 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences$$d2023-08-28 001009728 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bJ POWER SOURCES : 2022$$d2023-08-28 001009728 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2023-08-28 001009728 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2023-08-28 001009728 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2023-08-28 001009728 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2023-08-28 001009728 915__ $$0StatID:(DE-HGF)9905$$2StatID$$aIF >= 5$$bJ POWER SOURCES : 2022$$d2023-08-28 001009728 920__ $$lyes 001009728 9201_ $$0I:(DE-Juel1)IEK-1-20101013$$kIEK-1$$lWerkstoffsynthese und Herstellungsverfahren$$x0 001009728 9801_ $$aFullTexts 001009728 980__ $$ajournal 001009728 980__ $$aVDB 001009728 980__ $$aUNRESTRICTED 001009728 980__ $$aI:(DE-Juel1)IEK-1-20101013 001009728 981__ $$aI:(DE-Juel1)IMD-2-20101013
